Scientific Internship: Light-induced superconductivity

Date posted December 10, 2019
Type Scientific Internships

In this project you will explore how to dynamically and locally enhance (up to infinity) the electrical conductivity of materials inside an optical cavity. Recently, it was predicted that the charge transport can be pronouncedly enhanced inside an optical cavity, potentially enabling electrons to flow without dissipation. This transition to a superconducting state depends on the number of photons in the cavity, which can be controlled with a laser.  To explore this effect, you will measure the electrical conductivity of two-dimensional (2D) materials inside a laser-driven tunable cavity. For this purpose, you will first fabricate micron-scale electrodes to contact 2D materials; this part of the research will be done in collaboration with the Garnett group at AMOLF. Once you electrically contact the 2D materials and place them in a cavity, you will measure their conductivity while varying the cavity length and the laser power. You will perform these experiments across a wide range of temperatures, from ambient temperatures down to 4K.  To achieve this, you will use a new closed-cycle cryostat specially designed for experiments demanding extremely high mechanical stability; this is the first system of its kind in Europe, and second in the world.

About the group

In the Interacting Photons group we are interested in nonlinear and quantum behaviour of light.  We focus on tunable systems where light and matter interact strongly. We have strong connections to other groups in the Netherlands, France, and UK. You will have extensive support from the group leader and the technical staff at AMOLF. You will have access to a unique (in the world) tunable cavity setup in a closed-cycle cryostat, and a unique set of 2D materials synthetized at AMOLF.


You have a BSc in Physics or closely-related discipline. Lab experience is not necessary— you will get it here.  A background or strong interest condensed matter, quantum optics, or electronics is appreciated. This project involves collaborative work, so we are looking for a team-player.  Due to EU and Dutch regulations, you must be of EU nationality or enrolled in a Dutch university to apply for this position.

Terms of employment

At the start of the traineeship your trainee plan will be set out, in consultation with your AMOLF supervisor.
